Where do I start? This drama kept me engage the entire time. From the cases to the killings to the judgments, it was a masterpiece. Every thing about this drama was spot on. I loved how Justisia judged based on her law and not the law of the land because we all know that the law of the land does very little justice. She punished those who needed to be punished and I loved that for her. I also loved that despite falling in love with a human, she kept to herself. She was just as cunning as the sinners. Of course, when it comes to who Satan was, it was subtle in showing us who it was but it wasn't super obvious as well. It kept me guessing among the Jung family. I mean, that Assemblyman was suspicious along with his sons. So it was interesting to keep guessing among who the Jung men were.

Let's get started with the casts.
Park Shin Hye - Justisa and Kang Bit Na: wow, is all I can. She did an AMAZING job. This is by far her best performance since she started acting at a young age. She usually plays the same character, but she showcased her range with this one. I have always been a fan of hers, but she needs to play more roles like this. The badass woman who can defend herself. Of course, she is without faults. In the beginning, she was arrogant and rude, but she eventually started to understand humans and at the end, she did what she had promised the family. Her character arc was amazing. I enjoyed her smirk and fighting.

Kim Jae Young - Han Da On: Okay, not going to lie, I have never seen any of his dramas, but I thought that he was an awesome job. He was annoying at first, wanting to catch Kang Bit Na and use human laws against her, but once he joined forces with her, he started to understand that sometimes you can't use human laws on evil. I loved how with his eyes and tears, he can move the audience and the cold hearted Kang Bit Na. He went through a lot at a young age and he again lost the one who raised him and care for him, but he still wanted to be on the side of justice. His character arc was also amazing. He grew from being a one sided officer to understanding that the law may not always be on their side but he hopes that the law can at least mend the hearts of the victims.

Kim In Kwon - Mando: he is the funniest character of the entire drama. He was really put in a dilemma and he did what he can. I have always thought that he was a perfect match to Park Shin Hye. She had been driving him crazy since 2009 (if you know what I mean). Despite the fact that he was conflicted when it came to religion, being a demon himself, he was always loyal to Kang Bit Na. He went along with her shenanigans all the while trying to protect her the best he can.

Kim Ah Young - Arong: oh boy. Where to start with her. When we first met her, she was already suspicious to me. But she played her part so well. I understand that she wanted to do anything in her power to help Justista but betraying her idol was the most ridiculous thing she can do. I mean, Justitia has already told her to leave Han Da On alone, but she just couldn't trust her idol, so she went behind her back and got her almost killed. However, I did like that they made her realize what she did was wrong and stood by Justitia side as a loyal friend.

All of the guests did an AMAZING job. They were the perfect psychopath. They played their part very well and I can see that they have range to play someone who can come off as nice but is truly evil. They all deserve medals for their part in the drama. Some of them, especially the multiple personalities actor, outshined the main casts. I mean, they were just so awesome.

So, my rating. It started off as a 10, but I took 1.5 stars out because of the second part of episodes 14. I loved how she ended up dying, and then brought back to punish Jung Tae Gyu. However, she should have been sent back to Hell to punish the sinners and murders in Hell. After learning from what she had learned in the human world, she should have used that to rightfully punish the murders and not act like she did in the episode 1, but no, she asked Bael for three years and he willingly gave it to her. I love a happy ending, but I feel that for this drama, there shouldn't be a happy ending. This is not a fairytale drama.

The thing that I loved most about episode 14 is that it circled back to episode 1 when she told the kids about justice. That was a nice touch to the drama. However, I did not like the open end ending with the choice of either staying as a human by punishing 10 more sinners or going straight to hell. I wished she wouldn't even have that chance. I loved her but as I have stated, this wasn't a fairytale drama. It was a dark drama that has romance (which I still didn't agree with). Overall, I don't mind rewatching this again.
